Description

The wind-driven generator group wheel box studs is screwed into matrix method and instrument fast
Technical field
The present invention relates to a kind of installation method and less important work instrument of blower fan generating set, be particularly related to a kind of wind-driven generator group wheel box studs and be screwed into fast matrix method and instrument, mainly be adapted to the installation of large blade wind power generation set gear box studs, also can be used for the fixing of other stud.
Background technology
Large blade wind power generation set gear box construction bolt is studs, needs first studs to be screwed into main frame in advance in the process of gear-box assembling.Because studs does not clamp the position, can't use open-end wrench or sleeve to carry out pre-buried.Adopt at present hand to be screwed into main frame, speed is slow, and efficient is low.But because studs two all is screw thread, do not clamp the position, long-time hand is grabbed screw thread, the easy pain of hand.And it is unhappy to be screwed into speed, affects efficiency of assembling.Sometimes also need both hands to twist simultaneously studs, abnormally dangerous in work high above the ground like this.For improving the pre-buried efficient of studs, a kind of instrument that can use ratchet spanner studs to be screwed into fast main frame of necessary design.
Find some are arranged about the patent of wind-powered electricity generation unit lightning protection by the Searches of Patent Literature, have mainly containing of certain relation following with the present invention:
1, the patent No. is CN201010217983.6, and name is called " a kind of power tool of stubborn stud "
Patent of invention, this patent discloses a kind of power tool, a kind of power tool of stubborn stud specifically, it mainly is made of installing handle, stopping screw, notched thread bush, stud, workpiece, it is characterized in that: the bottom of installing handle links to each other with stopping screw, one end of notched thread bush is screwed in the bottom of installing handle by screw thread, the other end links to each other with stud.During use, the upper end of installing handle is linked to each other with electronic or pneumatic tools, before the work stud is screwed with in the thread bush of chamfering, start electronic or pneumatic tools after, double-screw bolt withstands on the lower end of installing handle very soon, stopping screw was run into notched thread bush and was blocked this moment, in electronic or process that pneumatic tools are rotated further, double-screw bolt was screwed in the workpiece.During counter-rotating, stopping screw is run into the another side of thread bush breach, makes thread bush break away from studs.
2, the patent No. is CN201220504897.8, and name is called the utility model patent of " studs quick-fastening and release ", and this patent discloses a kind of studs quick-fastening and release.It comprises and holds out against screw and attaching nut, described hold out against screw comprise the upper end screw head, the screw rod of lower end is processed with external screw thread outward, described attaching nut inside is processed with undercut, the bottom opening through hole of undercut all is processed with internal thread in undercut and the through hole.Employing holds out against screw and screws in the attaching nut, the attaching nut is screwed into the stud that need tighten up, and this kind mode studs tightens up effective, has simultaneously the function that stud is got loose.
3, the patent No. is CN200920162252.9, and name is called the utility model patent of " dedicated assembling tool for stud bolts ", and this patent discloses a kind of dedicated assembling tool for stud bolts, is used for solving the problem of the bad assembling of decelerator stud.For a long time, when the assembling stud, the method that adopts is to be tightened in mutually two nuts on the stud, then pull a top nut, following nut is fixed with spanner, and stud is screwed in the bolt hole, then more top nut is back-outed and is taken away, this just needs two people cooperation to finish, and assembling is difficulty relatively.The technical solution used in the present invention is: dedicated assembling tool for stud bolts is comprised of two half mould nuts, bearing pin, left and right pliers handle, the thread form of nut is consistent with the stud that assembles with size, two half mould nuts are welded on respectively left and right pliers handle upper end, and left and right sides pliers handle is linked together by bearing pin.
Although above-mentioned these patents have all related to the studs quick-fastening and have got loose, and all still have some problems, can not be used for the wind-driven generator group wheel box studs and be screwed into fast, therefore necessary this is improved.
Summary of the invention
The object of the invention is to be screwed into fast the existing some shortcomings of matrix method for existing wind-driven generator group wheel box studs, propose a kind of new wind-driven generator group wheel box studs and be screwed into fast matrix method and less important work instrument, utilize the method and less important work instrument can realize that studs is screwed into matrix fast.
Goal of the invention of the present invention realizes by the following method: a kind of wind-driven generator group wheel box studs is screwed into the matrix method fast, utilize ratchet spanner and the integration of operation of a less important work instrument, fast studs is screwed into the wind-driven generator group wheel box matrix; Described ratchet spanner and the integration of operation of a less important work instrument are that ratchet spanner is enclosed within on the less important work instrument, again with the less important work tool cover on the wind-driven generator group wheel box studs, driving the less important work instrument by the rotating ratchet spanner rotates, drive studs by the less important work instrument again and rotate synchronously, realize that studs is screwed into matrix fast.
Further, one end of described less important work instrument is by the tight studs of screw thread handle, the other end of less important work instrument links to each other with ratchet spanner by a cubic counterbore, the rotating ratchet spanner drives studs by the less important work instrument and rotates synchronously, realizes that studs is screwed into matrix fast.
